Not a quote, but a symbolic action. He threw away his gold medal from the 1960 Olympics, out of understandable anger at segregation in America. Many years later, he said he regretted throwing it away, and a replacement medal was forged for him.

Ah. Well I heard a few more quotes on TV today. “I make medicine sick and can drown a drink of water” and also “I’m so fast I turned off the light switch in my hotel room and got into bed before the room was dark.”
